To4 all whom may concern:

Be it known that I, HORACE R. ALLEN, a citizen of the United States. residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Ghromatic Printing Apparatus, of which the following is a specification.

The invention relates to chromatic printing devices; and it consists in the novelty of construction, arrangement, and adaptation of parts, as will be more fully hereinafter set forth, and specifically pointed out in the claims.

The object of the invention is to provide a device which shall automatically mark an advertisement or the like in an ink different in color from that used on the printing-roller. Various devices for similar purposes have before been devised. I employ the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a vertical section of the entire machine of one form of construction; Fig. 2, a top view of the same machine as it appears when the electrotype plate or top of the machine is removed. Fig. 3 is a vertical section showing an inking-ribbon in connection with the lever and plunger.

Similar letters refer to similar parts throughout the several views.

In Fig. l A is the electroplate containing` the electrotyped matter to be printed in the marked article. This plate, instead of being blocked on a solid wood or metal base, as is customary with electrotypes, is placed over and forms the lid of a hollow metallic box, S S, Fig. l, and S S L L, Fig. 2, which serves as a reservoir for a colored ink.

The sides of the plate A rest rmly on the sides L L of the box, Fig. 2, and when necessary additional rmness may be given the plate by running supports up from the bottom of the box. Within this box a double lever, D D, Figs. l and 2, joined by the cross-arm I, Fig.` 2, is, adjusted, and works freely onthe pivot E, Figs. l and 2. v

The cross-arm I, connecting thetwo parts D D of the lever, is provided with two rigid pins, F F, Fig. 2, placed near the ends of the crossarm. These pins give a bearing to the depressing-plunger G, which rests on and is supported by the pins. The plunger G is free to move up and down, and to insure its moving in a firm and even manner its ends are grooved.

to receive the guides J J, which project from the sides of the box. The plunger G is made to project above the surface of the type, and may be made rounding to guard againstinjuring the rollers, or it may be covered with a row of type.

On the opposite end of the lever from the arm I is attached the marker C, Figs. 1 and 2. This marker is a strip of any form, and is allowed to stand above the lever D D just high enough to bring the upper edge against the paper when the plunger G is depressed to the level of the type A. V

H, Figs. l and 2, is a stift' spring, one end of which is fastened securely to the bottom of the box and the other allowed to bear against the cross-arm I on the short end of the lever D, keeping the long end of the lever, with its attached marker, always against the bottom of the box, unless force enough is brought to bear, through the medium of the depressing device G and the pins FF, on the short end of the lever to overcome the tension of the spring H. i

Suitable openings are left in the lid or plate A to accommodate the working of the parts C and G.

This style of machine can only be vused on printing-presses having a fiat bed. Its practical operation is as follows: The printing device is placed in the form to be printed, and is locked up firmly like a commonelectrotype. The form is then placed on the press, and before the press is started the hollow box or reservoir under the plate A, in the printing device, is filled with common fluid ink of any desired color, 'as carmine. The press is then started, and to keep the ink in the reservoir from slopping the space below the lid may be filled with sponge. ject above the surface of the type to such a distance that when it is forced down by the platen of the press to the level of the type the marker C on the opposite end of the lever D will be raised to a level with the type.

The ink-rollers, owing to their yielding nature and to the stiffness of the spring H, do vnot in passing over the form press the `device G down far enough to raise the marker C to the The device G should pro- 4 IOO surface, but when the printed impression is made the force is sufficient to bring the device G down to a level with the type, thereby raising the marker C, which retains enough ink on its upper edge to mark the paper. p

p In Fig. 3 I show the same arrangement of parts with an endless inking-ribbon, R. This ribbon winds upon one roller, P, and off another roller, O, or vice versa, and'each roller has a ratchet-face, the ratchets of one roller being arranged reversely to those of the other roller. A pivoted pawl, M, may be thrown at will so as to engage either roller, and the ribbon passes over the marker G, and along the bottom of thl reservoir, to insure that it will reach the 1n It will be observed that the lever having' 1. In a printing device, thei'combination of a box, an electroplate secured thereto, a lever fulcrumedin such boX, carrying a marker, and a plunger acting upon such lever, substantially as set forth.

2. In combination with an ink-holdingbox or 'reservoir and an electroplate secured thereto above the surface of the ink, a lever fulcrumed in such box and carrying a marker, and a plunger acting upon such lever to throw the marker against the paper being printed, as herein described.

3. In combination with au ink reservoir or box and attached electroplate, as described, a lever pivoted in such reservoir or box and carrying a marker, a spring to hold themarker end of the lever to the ink, and a plunger acting upon such lever to overcome the action of the spring and throw the marker against the paper being printed, as setV forth.
